virtue oled reliability

i have a nt11, and was wondering what the oled board is like, i see it says it has the same batterly life of a regular 9 volt, but the idea of a not immediately replaceable power source scares me. what are your thoughts on this, or is there anyone who has one that can provide some insight? my main concern is that the marker will go down in a tournament, or that like other lithium batteries, the more times you charge it, the less time it will hold each charge. any insight would be greatly appreciated, thank you.

The Virtue OLED board is really reliable. You can charge quite often and I haven't seen any loss of charge holding. You can get a full charge in 35-40mins. From what I experienced, my charge would hold up for at least 2 weeks, but I usually charge my battery right as I'm getting ready for practice.

I had some problems with my virtue board switching on and off randomly (with no pattern to what was wrong). So I had to swap it for a new one, since then it has been running flawless. Battery life is very good, it can last for about 3 weeks with playing 3 times a week. But my advice is save the money to buy something else, having a screen is pretty cool and all, but you never really change the settings and "upgrading" a high end markers isn't necessary. It just allows more things to go wrong on the day where you need your marker the most.

my charge held up to 3 weeks and still had about 1/3 left.
if u do play psp sometimes in tournys if they check, it reads that the rof is faster than 12.5 so its nice to have it and change it real quick.
other than that, the best thing is the rechargable battery that last forever

thank you guys, i guess i should have specified, i have an nt coming in with the virtue oled board in it, and i was trying to decide whether or not i should get rid of it for a virtue redifined board or stock board, or just keep the oled board.
